UTRICULARIA. 



■line, that feveral of thefe beautiful novelties were neceflarily 

 fcft uodetermined. Any botanift pofleffed of an extenfive 

 herbarium, cannot fail to acknowledge that he is reduced 

 to the fame neceflity ; for Vahl, who has given the bed 

 general account of the fpecies of this genus, confefles that 

 he had feen many more, that were undoubtedly diftinft, but 

 for which he could not hit upon fpecific charafters, fuch 

 being fcarcely difcernible in dried fpecimens. None of thefe 

 plants appear capable of cultivation, at lead none have as 

 yet been introduced into gardens. Vahl diftributes them 

 into four feftions, which we (hall adopt, with fuch addi- 

 tions and corredlions as we are enabled to attempt. Our 

 kind friend Dr. Afzelius has fupplied feveral apparently 

 new fpecies from Sierra Leone, which, as far as poffible, 

 we fhall try to reduce to order. It is very probable, efpe- 

 cially as the whole genus is more or lefs aquatic, that the 

 fame fpecies may occur in the old and nevi' continent, or 

 other widely diftant countries. But as we find not a fingle 

 inftance of this kind recorded, we (hall not venture to refer 

 any of our unknown fpecies, from one quarter of the globe, 

 to the defcriptions of any found in another. The Guinea 

 fpecies, for inltance, we muft prefume to be all different 

 from thofe of New Holland, or of South America. The 

 herbarium of the younger Linnaeus contains perhaps eight 

 fpecies, without any indication of their native country, or 

 any mark whatever. Thefe muft of courfe be omitted, as 

 they may poffibly be New Holland fpecies, communicated, 

 like many other plants, to their late poffeflbr, by his friend 

 Solander ; and it would be too precarious to refer them, by 

 examination in their dried and imperfeft condition, to any 

 of Mr. Brown's defcriptions, however excellent the latter 

 may be with a reference to living plants. Vahl has a nu- 

 merous feftion, fifteen fpecies, faid to have no leaves. Such 

 indeed is the frequent appearance of many of the plants, in 

 the dried ftate, in which alone he had an opportunity of ex- 

 amining them. But Mr. Brown, who faw fo many alive, 

 mentions none that are truly leaflefs, though he fa)-s the 

 foliage is often deciduous in thofe with undivided leaves. 

 There is great likelihood, therefore, that feveral of Vahl's 

 laft feftion may properly belong to his firft ; as proves to 

 be the cafe with his uUginofa, aflerted by Mr. Brown 

 to be either graminifo/ta, or cyanta, he could not pofitively 

 fay which. For the reft we can only truft to his opinion or 

 obfervation. 



Seft. 1 . Leaves radical, ftmple. 



1. U. alpina. Alpine Bladderwort. Linn. Sp. PI. 25. 

 Willd. n. I. Poiret n. i. (U. montana ; Jacq. Araer. 7. 

 t. 6. " U. unifolia ; Fl. Peruv. v. I. 20. t. 30. f. b.") — 

 Neftary awl-(haped. Stalk moftly fingle-flowered. Roots 

 tuberous. Leaves elliptic-lanceolate. Lips of the corolla 

 nearly equal. — Gathered by Jacquin, on the loftieft moun- 

 tains of the ifland of Martinico, in wet expofed Ctuations, 

 flowering in February. Root fibrous, furnithed with many 

 fmall elliptical knobs. Leaves two, radical, ftalked, acute, 

 entire, an inch and a half long, fmooth, ftiining, rather 

 fle(hy. Flotuer-Jialks fohtary, fimple, ereft, fmooth, fix 

 inches high, bearing two oppofite braSeas, and one, fome- 

 times two, large handfome ^o'zi'^v, above an inch in dia- 

 meter, whofe corolia is white, the calyx and nedary only 

 being (lightly tinged with yellow. Jacquin. This feems 

 to have the largeft Jloiver of any known fpecies, except 

 the following. 



2. U. montana. Mountain Bladderwort. Poiret n. 2. — 

 Neftai-y conical, acute. Stalk naked, moftly two-flowered. 



■ Roots verficular. Leaves radical, ovato-lanceolate i-Native 



of Martinico. This might be fuppofed the fame as the lafl, 



'4t 



but Poiret fays " the lower haves, or rather the roots, arf 

 brown, confifting of numerous fpreading fibres, a little 

 comprefled, laden with ftiort fetaceous filaments, whicli 

 bear a few minute globular veficles. Radical leaves ftalked, 

 at leaft an inch long, bluntifh, fmooth, fleftiy, entire, with 

 fine branching veins. Footjlalhs full as long as the leave?. 

 Floiver-ftalks fix or eight inches high, bearing feveral dif- 

 tant, minute, membranous, oval-oblong, fcaly braSeas, and 

 divided at the top into two widely fpreading branches, each 

 bearing one ^oiyf/-, an inch at leaft in diameter, apparently 

 white ; with a tinge of blue. Calyx-leaves oval, obtufc, 

 very thin, broadelt at the bafe, marked, like the corolla, 

 with ftraight longitudinal lines. The two lips of the latter 

 are flat, very broad, nearly equal, rounded, almoft entire. 

 Spur rather fliorter than the lips, awl-ftiapcd, flightly 

 curved." 



3. U. hifpida. Branched Rough Bladderwort. La- 

 marck Illuftr. v. I. 50. Vahl n. 2. Poiret n. 3. — " Nec- 

 tary awl-ihaped, reflexed. Stalk branched ; hifpid in the 

 lower part. Leaves hnear. Calyx-leaves roundifli." — 

 Found in Cayenne, by M. Richard. Roots fafciculated, 

 fubdivided, hardly an inch long. Leaves three, radical, an 

 inch long, acute, fmooth, without rib or veins, each taper- 

 ing at the bafe into a footftalk. Flotuer-Jlalk half a foot 

 high, or more, round ; fmooth in the upper part, where it 

 divides into two or three zigzag branches ; partial Jlalks 

 four or five, diftant, fingle-flowered. Fluwers Imall. A'^r- 

 iary nearly the length of the petal. Vahl. 



4. U. volubilis. Twining Bladderwort. Brown n. 3. — 

 " Stalk twining, round, about two-flowered. Lips of the 

 corolla undivided ; the upper wedge-fliaped ; lower very 

 large, hatchet-fliaped. Spur deicending, obtufe, deprefted. 

 Calyx obtufe." — Gathered by Mr. Brown, on the foutheru 

 coaft of New Holland. 



5. U. fpiralis. Spiral-ftalked Bladderwort Stalk 



twining fpirally, with feveral diftant flowers. Lower lip 

 very large, cloven. Spur defcending, awl-fliaped, pointed. 

 Calyx acute. — Native of Sierra Leone. Afzelius. The 



Jlalk of our only fpecimen is a foot or more in height, flen- 

 der, fmooth, unbranched, twining round the ftem of a grafs, 

 and bearing ioMT Jloivers, two inches at leaft afunder, except 

 the two uppermolt. Y-ach Jlotuer ftands on a flender partial 

 ftalk, half an inch long, accompanied by two fmall ovate 

 hraSeas. The fpur is very ftiarp, the length of the partial 

 ftalk, and rather longer than the lower lip. The colour of 

 the jloivers, as far as can be judged, is purplifh. We have 

 feen no leaves nor root, and therefore place this fpecies here 

 merely from the agreement of its Jlem with the laft, of which 

 we have but few examples. 



6. U. fpeciofa. Handfome Bladderwort. Brown n. 4. 

 (U. dichotoma ; Labillard. Nov. HoU. v. I. II. t. 8. 

 Poiret n. 9.) — Stalk ftraight. Flowers oppofite. Upper 

 lip abrupt ; lower very large, hatchet-ftiaped, undivided. 

 Spur obtufe. Leaves hnear-fpatulate, ribbed ; tapering at 

 the bafe. — Native of New South Wales and Van Diemen's 

 ifland. Root of many tufted fibres, bearing fmall knobs. 

 Leaves radical, fpreading, above an inch long, immerfed in 

 water, as well as half ihe Jlalk, which is twelve or fifteen 

 inches high, quite fmooth and naked till within three or four 

 inches of the top, where it bears about three diftant pairs of 

 oppofite, ftalked, brafteated, large and handfome purple 

 flntuers ; whofe palate is bearded ; fpur thick and abrupt, 

 half the length of the lower lip; one leaf of the calyx 

 cloven.
